Licensing
Do you need a license in Mississippi?
This is an important distinction in Mississippi: while cleaning is itself a service skill, work that installs, alters, or services HVAC mechanical or refrigerant components generally requires a mechanical or HVAC license, and on residential projects mechanical and HVAC subwork must be licensed regardless of dollar amount. A NISCR certificate is a professional credential, not a government license. Always verify the line between cleaning and licensed mechanical work with the Mississippi State Board of Contractors and your local authority before taking jobs.
A NISCR Certificate of Completion confirms completion of NISCR training and examination. It is a professional credential, not a government license. Where local law requires a license to perform a service, the technician is responsible for obtaining it.

Curriculum
What you’ll learn
- Clean and rinse evaporator and condenser coils without bending fins or damaging the coil, using the correct foaming and no-rinse cleaners for each coil type.
- Disassemble, clean, and rebalance blower wheels and motor assemblies to remove caked debris that chokes airflow and wastes energy.
- Service condensate drain pans and lines — clearing clogs, treating biofilm, and verifying proper slope and drainage to prevent overflow and microbial growth.
- Open, inspect, and clean air-handler interiors and plenums, including interior insulation surfaces, following containment and source-removal standards.
- Set up negative-air containment and HEPA collection so dislodged debris is captured rather than spread through the occupied space.
- Identify and document microbial contamination, biofilm, and rust, and know when to refer remediation beyond routine cleaning.
